T 0 all whom it may concern:

Be it known that I, Join: C. MULLINS, Jr., a citizen of the United States, and a resident of (oeburn in the county of \Vise, and State of Virginia, have invented certain new and useful Improvements in Thrust- Bearings of Ford Motor-Shafts, of which the following is a specificatiom y present invention relates generally to thrust bearings and more particularly to a thrust bearing for the motor shaft of Ford automobiles, in connection with which it is a well known fact that considerable trouble is now experienced, due to endwise movement of the motor shaft from wear, permitting the contact points of the maneto, a portion of which rotates with the y wheel secured on the motor shaft, to become improperly spaced, and the object of my pres-' ent improvements is the provision of a simple, ineiipensive arrangement which mayv be readily installed and which will operate effectively and efficiently to avoid these disadvantages.

In completing my invention, I propose the use of an arrangement, involving simply the addition of a bearing installed and effectively secured to the timing gear housing of a Ford motor and the substitution of a lower fan belt pulley for the one usually employed, the nature of which will admit of its cooperation with, and allowance for the above mentioned bearing plate and the bearings disposed between this plate and the inner wall of the pulley.

lVith the above general statement, it is believed the invention maybe thoroughly understood and readily appreciated from the following description thereof and the accompanying drawing which forms a part of this specification and in which,

Figure 1 is a side view partly in elevation and partly broken away and in section of the forward portion of the timing gear housing, illustrating the motor shaft provided with my improvements,

Fig. 2 is a vertical transverse section taken substantially on line 2-2 of Fig. 1,

Fig. 3 is a bottom plan view of the bearing plate, and

Fig. 4 is an elevation looking at the inner face of my improved lower fan belt pulley.

Referring now to these figures, have plate which may bev which may the timing gear housing of a Ford motor through which the forward portion of the Patented Oct. 11. 1921.

gear housing to In accordance with my invention, I contemplate the removal of the usual lower fan belt pulley and the disposition upon the forwardly projecting end 13 of the motor shaft of a bearing plate14, preferably of circu lar form, having an annular groove 15 in one face, as best seen in Fig. 2 and provided with angular extending wings 1G projecting from its opposite face and z )ertured as at 17 so as to register with the ail apeitures of the upper and lower sections of the timing gear housing, as seen in Fig. 2, in order to receive the bolts 18 and thus rigidly secure the bearing plate 14 against the front face of the timing gear housing and around the shaft 11.

I further contemplate the substitution of a lower fan belt pulley 19 in place of the usual one, the hub portion 20 of which is bored to receive the shaft end 13 and is integral with a wall 21 at the inner side of the pulley, whose outer face opposes the outer face of the bearing plate 14 and has an annular groove 22, as seen particularly in Fig.

jacent bolt receiving 4, which is complementary to the annular groove 15 of the bearing plate, whereby to form a ball race for the reception of antifriction balls 23. The hub portion 20 of this pulley has diametrically opposed openings so arranged as to receive the usual connect ing pin 24 which passes also throu h the shaft end 13, these openings of the ub 20 being so arranged as to allow for the space re uired by the bearing plate 14.

n this way it is obvious that my invention provides or an effective, efiicient thrust hearing which will avoid the disadvantages of endwise movement of the motor shaft 11, due to the wear of the parts, as well as one be readily and quickly installed, and will be a great benefit to the general operation of the motor in connection with which it is utilized.

claim 1. The combination with the timing gear housing and motor shaft of a Ford motor,

the former of which has a series of connect ing bolts and the forward end of which motor shaft projects slightly be end the timing gear housing, of a bearing plhte disposed on the shaft and secured to the timing gear housing by means of the said bolts of the latter, a lower fan belt pulley secured upon the projecting end of the shaft and having its inner wall opposing said bearing plate, and antrfriction membersbetween the said pulley wall and the bearing plate, as and for the purpose described.

2. The combination with the timing gear housing in bolted upper and lower sections and the motor shaft whose forward end projects slightly beyond the timingvgear housing, of a bearing plate disposed on the shaft, and against the timing gear housing, having apertured extensions, the apertures of which are arranged to register with and receive certain of the bolts of the timing gear housing, said plate having an annular groove in its outer face and a pulley secured upon the projecting portion of the shaft, having a wall at its inner side provided with an annular groove facing, and cooperating with the groove of the bearing plate, and anti-friction members disposed in the grooves, as described.

In testimony whereof I affix my signature.
